wifi seems to cause a good deal of wakelocks if your not actually connected to a network, so I would turn it off when your not on one.

But yea, battery seems mediocre.........at least compared to this WIUI build i tried out. Basically MIUI V4 beta 3 from WIUI, battery life on that was amazing even though its based off CM9, which I really don't understand. I was getting Gingerbread like battery life/stock roms. I could get around 5 hours of display usage after like almost 24 hours on battery

How did you manage to get that brilliant battery life? Even when i'm on Samsung original 2000mAh battery, from 100%, my CM9 Nightly build 29th Feb goes down 1% close to every hour, lowest screen brightness, flight mode, no BT, GPS and Wifi. As for now, i get 21hr before the battery died, screen on 1hr 52min, betterbatterystat says wake lock is download manager (4min 12sec), in Battery Usage, Android OS is on the top hooking 84% and getting 21hr 43min Keep awake! But funny thing is inside the battery usage graph, i don't see any funny random awake. so what could really be draining my battery?

I had a similar experience on that build. However I'm on the experimental build now and its magic. The battery life is somewhat back to factory standard. Although I see lots of threads about wake locks which I can only assume are issues affecting battery life. I'm therefore confident that they will endeavour to improve this more and more each build.

I reccomend getting off that build. If you don't want experimental at least go to 03032012.

I'm having problems with the stock keyboard when typing in Danish, with auto-corrections on. With certain keystroke combinations, the keyboard force closes; eg. when I want to write 'little' in Danish (lille), it force closes after pressing the i-button.

Hey guys. Been reading thru the thread. I'm on codeworkx custom build with how codecs working and lph radio. I haven't been able to get GPS working at all on this build or any of the previous cm9 builds. Any tips? I know it didn't used to work for many ppl but I see reports that GPS was fixed. Mine never seems to work. The GPS icon doesn't even flash in and out like its supposed to
In the notification drawer it always just says searching for GPS..

As i said, it was on the WIUI which is a ROM based off MIUI which is based off CM9. Idk what MIUI/ the guy WIUI are doing, but they somehow tweaked CM9 to offer amazing battery life.

I'm back to CM9 since it's nightlies and battery life is better than before, i'm at 8 hours on battery and 36minutes of display time. Nothing close to what I was getting on WIUI/MIUI, but its better than it used to be. Standby is better but still not that great.

I might go back after they implement the HW codecs in their MIUI/WIUI build and just use an ICS launcher

CM9 is still awesome though, just wish battery was a bit better. It gets me through the day still.......I use anker 1900mah btw, but still nothing compared to samsungs 2000mah. I'd say the anker is really around 1800mah but its good for only $20 for 2 + charger

Ahh i see, so I'm not the only facing the high Android OS percentage and battery drain, my best record on 2000mAh samsung Battery, CM9 Nightly build 29th Feb, was 1day 2hr 54min idle, 2hr 16min Screen on, 36min Cellular standby, 13min Wifi, the rest are mostly screen off and flight mode. Battery died after than in a single charge from 100% to zero.

I tried installing the latest nightly build to my S2 (i9100P), via CWM, but it won't flash. I keep getting a '(Status 7)' error code, right after it lists other various S2 model types (i9100P) not included.

My guess is that the i9100P model is not compatible with the CM9 builds. Would that be right?

If so, is there any way around this? Maybe a workaround of some sort.

If not, how do I go about requesting that this is added to future builds?
